Genetic polymorphisms in the central repeat region of Myanmar PfCSP. a Polymorphic characters in the central repeat region of Myanmar PfCSP. Sequence alignment revealed that the central repeat region of Myanmar PfCSP showed polymorphic characters with 14 distinct haplotypes. Residues identical to those of the 3D7 PfCSP reference sequence (XM_001351086) are shown by dots. The dashes represent gaps introduced to maximize the alignment. The NANP repeat and NVDP repeat are indicated as one and two, respectively. The two new tetrapeptides, NTNP and NANS, are shaded with yellow. The number of haplotypes indicated the number of Myanmar PfCSP belonging to each haplotype. b Frequency of number of repeats in the central region among Myanmar PfCSP
